I mean the video black screen and no sound, only flashing up whrn stop is pressed.

I use hdmi audio already so that "change" would not affect me.

Ah OK, I see. I guess it must be a bug when using HDMI audio then, not just if it's set to HDMI audio when it should be set to analog (in my case, I'm using a HDMI switch with a HDMI->DVI lead to the TV, so there's no way for the audio to get to the TV via HDMI).

I guess you could try changing it to analog, even if you don't have it connected, to check whether that fixes it, which would at least confirm that is the problem.
